Saffron

What is saffron, and why is it so expensive?

Saffron consists of the dried stigmas of Crocus sativus, an autumn flower. Each flower bears only three stigmas, which must be hand-picked in the morning, flower by flower, then trimmed and dried on the same day. Approximately 150,000 flowers are needed for one kilogram of dried saffron, and about five kilograms of fresh stigmas for one kilogram of finished product.

Everything else follows from this: no mechanization has replaced manual labor, the harvesting window is short, and the yield per hectare is low. Saffron is therefore the most expensive spice in the world by weight — and this value is precisely what makes the market vulnerable to adulteration.

A distinction must be made from the outset: most people looking for saffron are looking for a culinary spice, sold in threads or powder. This section deals with something else, the standardized extract as a dietary supplement, which follows different reading rules. And a clarification that applies to the entire page: no health claims are authorized in Europe for saffron, as plant-related claims have never been validated. Therefore, we will not write anything about what this plant would do in the body.

What is a standardized extract, and what are the markers?

Standardizing an extract means guaranteeing a minimum content of a molecule chosen as a marker. Without a measured marker, an extract is just a powder whose richness is unknown. Saffron has three, each responsible for a sensory property:

• Crocins, carotenoid pigments, responsible for the coloring power — that intense orange-yellow.
• Picrocrocin, responsible for the characteristic bitterness.
• Safranal, responsible for the aroma. It does not exist as such in the flower: it forms from picrocrocin during drying, which explains why the quality of saffron depends as much on drying as on harvesting.

For the spice, these three markers are measured by the ISO 3632 standard, by spectrophotometry: absorbance at 440 nanometers for coloring power linked to crocins, at 257 nm for picrocrocin, at 330 nm for safranal. Three categories result from this, Category I requiring more than 200 at 440 nm, II more than 170, III more than 120.

A point that few sellers specify: this standard applies to the spice, not to concentrated extracts sold in capsules, which are characterized differently by a percentage of marker determined by chromatography. Hence the most useful rule on this page: two extracts are only comparable if they are standardized on the same marker, measured by the same method. A percentage of safranal and a percentage of patented complex are not comparable, even if the numbers look similar.

Why is saffron so often adulterated?

Because the raw material is expensive and fraud is profitable. Three families of cases are documented. Substitution replaces all or part of the saffron with a visually similar and worthless material: safflower — sometimes sold under the misleading name "bastard saffron" —, marigold, turmeric, dyed corn stigmas, colored paper threads. Weighting increases the weight sold by adding water, glycerin, honey, or salts: the product remains saffron, but you buy less than you think. Coloring adds a synthetic dye to mediocre saffron to give it the intensity of a high-end product.

A simple rule for the spice: powder is much easier to adulterate than threads, because nothing can be observed in it. For a supplement in capsules, you see nothing at all — which entirely shifts confidence to the measured marker and traceability.

How to identify a reliable extract?

1. The species and part used: Crocus sativus L., stigma. A label that only says "saffron" leaves an open question.
2. The marker, named and dosed, with its percentage — safranal, crocins, or an identified complex. This is the only number that allows for comparison.
3. The dose per serving, in milligrams of extract, with the extraction ratio if indicated. A ratio alone, without a marker, says nothing about the richness of the product.
4. Traceability: origin of the raw material, and if applicable, name of the patented extract, which allows its documentation to be found. An identifiable extract is verifiable; an anonymous extract is not.
5. Absence of health claims. A brand that promises an effect on a body function falls outside the European framework, and this is a signal about its general seriousness.

What is the regulatory status, and what precautions should be taken?

Crocus sativus L. is indeed on the French list of plants that can be used in food supplements, established by the decree of June 24, 2014. However, the plant is accompanied by a reference to health recommendations, i.e., restrictions on use to be observed: it is not in the category of plants without reservations. As for claims, the situation is clear — none are authorized, as botanical claims have remained awaiting evaluation at the European level.

• Pregnancy and breastfeeding. Saffron is traditionally not recommended during pregnancy at doses exceeding culinary uses. This contraindication must be respected.
• High doses. At quantities much higher than any food use or supplement dosage, saffron is toxic. Never exceed the dose on the label and do not combine several products containing it.
• Ongoing treatments. In case of long-term treatment, particularly affecting the nervous system or coagulation, medical or pharmaceutical advice is necessary before starting. Never interrupt a treatment to substitute a food supplement.
• Children and adolescents: this section is for adults.

Frequently Asked Questions

What is the difference between culinary saffron and a supplement extract?

Two distinct products from the same plant. The spice comes in threads or powder, is bought by the gram and is appreciated for its coloring power, bitterness, and aroma — the three properties measured by the ISO 3632 standard. The supplement extract is a concentrated preparation, dosed in milligrams and characterized by a percentage of marker. The criteria for choice have nothing in common: ISO category and appearance of threads on one side, measured marker and traceability on the other.

What are the benefits of saffron?

We will not answer, and this is deliberate. No health claims are authorized in Europe for saffron: plant-related claims have never been validated and remain awaiting evaluation. Any sales page that claims an effect on a body function falls outside the regulatory framework. What we can describe is limited to what the product is — species, part used, markers, concentration, origin. For an expected benefit, the conversation belongs to your doctor.

How long does saffron take to take effect?

The question assumes an effect that we are not allowed to advertise: no claim being authorized for this plant, no deadline can be promised, and a seller who gives you one falls outside the legal framework. What can be honestly said is that published protocols on standardized extracts generally span several weeks, not a few days — this is an observation period, not a promise of results. If you expect something specific from a supplement, the right approach is to discuss it with a doctor before buying it, not to count the days afterward.

What are the dangers and side effects of saffron?

At culinary quantities and supplement doses, saffron is well tolerated; reported discomforts are mainly digestive, sometimes with nausea or headaches. The serious point is elsewhere: at very high doses, far above any food use or supplement dosage, saffron is toxic. This is not a cautionary statement: it is the reason why the plant is on the French list with a reference to health recommendations, and not without reservation. Three rules follow: never exceed the dose on the label, never combine two products containing it, and exclude supplementation during pregnancy and breastfeeding.

Does saffron thin the blood?

No claim to this effect is authorized, and we will not claim any such thing. Nevertheless, a precaution exists, and it is written above: in case of treatment affecting coagulation — anticoagulant, antiplatelet agent — medical or pharmaceutical advice is necessary before starting supplementation. The same applies before surgery: report any intake to the anesthetist. Caution is not proven effect, but in this area, caution comes first.

How to consume saffron?

It all depends on which one we are talking about. The spice is prepared by infusion: a few crushed threads, left for twenty minutes to an hour in a lukewarm liquid — water, milk, broth — before being added to the dish with their infusion. Thrown directly into a boiling preparation, the threads do not release their color and aroma well. The supplement extract is not cooked: it is a capsule or tablet, to be taken according to the manufacturer's instructions, with a glass of water. Do not confuse the two logics: a few milligrams of concentrated extract have nothing to do with a pinch of spice in a risotto.

When to take saffron, morning or evening?

No data indicates one time as superior to another, and it would be dishonest to invent one for a plant for which no effect is recognized. Simply follow the manufacturer's instructions, who designed their dosage in this way. The only valid recommendation concerns tolerance: during a meal, to limit digestive discomfort. And the really important point is not the time but regularity and adherence to the dose.

What is the dosage for extracts?

Follow the manufacturer's instructions, without exceeding them. Extracts on the market are dosed in tens of milligrams per serving, which seems little but corresponds to a highly concentrated raw material. The comparison is not made on the number of milligrams but on the marker content: a more weakly dosed but better standardized extract can provide more than an extract showing a higher number.

What is the best saffron?

The answer differs depending on the product. For the spice, the objective criterion is the ISO 3632 category: Category I requires a coloring power greater than 200 at 440 nm, compared to 170 for II and 120 for III. Always prefer threads to powder, which is much easier to adulterate. For a supplement extract, the ISO category does not apply: what matters is the named and dosed marker, the species and part used, and the traceability of the raw material. As for the origin — Iran, Spain, Morocco, France — it says something about the sector, never about the richness in markers: two saffrons from the same country can be worlds apart.

How to recognize real saffron threads?

Some benchmarks, with the caveat that no home test replaces an analysis. The authentic thread is trumpet-shaped, flared at one end, of a uniform dark red; a dyed stigma often has too homogeneous a color or a poorly concealed pale yellow base. Immersed in cold water, it slowly releases its color, remaining red itself: instantaneous coloring and a thread that whitens indicate an added dye. The taste is bitter, never sweet — safflower, on the other hand, is bland.

How much does saffron cost?

It is the most expensive spice in the world by weight, and the reason is arithmetic: approximately 150,000 hand-picked flowers are needed for one kilogram. The price is therefore by the gram, never by the kilo. A more useful reasoning than the displayed price: beware of what seems cheap. In a sector where substitution with safflower or turmeric is documented, saffron significantly cheaper than the market raises a question before it is a bargain. For a supplement extract, do not compare prices per pot: relate them to the indicated daily dose and marker content, otherwise you are comparing two different things.

Is organic saffron of better quality?

Certification relates to the cultivation method, not to marker richness or authenticity. It provides a guarantee of agricultural practices and enhanced traceability, which is not insignificant in a sector exposed to fraud, but it does not replace marker dosage. Two independent criteria, to be checked separately.

Can it be combined with other plants?

Many market formulas already do so. Two rules: read the complete list, each plant adding its own precautions and contraindications, and do not combine several products containing the same species. If you are interested in plants, our ashwagandha section is subject to exactly the same framework — listed plant, no claims authorized, marker to be checked on the label.

Where to buy saffron?

For the spice, from a specialized grocer or directly from a producer, in threads and not in powder. For the supplement extract, on this page — with shipping throughout France and Europe — or in our Vendargues store, about ten minutes from Montpellier, with pickup within 2 hours. In a sector so exposed to adulteration, the location matters less than what the label bears: species, part used, dosed marker, origin. This is exactly what we check before listing a product, and what we will review with you at the counter.

What brands do we offer?

We select references whose label names the species and part used, indicates a dosed marker and an identifiable extract, and refrains from any promise of effect. These include Nutriting. This section is alongside ashwagandha, maca, fenugreek and our superfood ingredients, all of which raise the same question of marker and traceability; the rest of our micronutrition is in multivitamins and sports nutrition.

A question in store near Montpellier?

In a sector so exposed to adulteration, knowing what you are buying matters more than elsewhere. Our store in Vendargues, about ten minutes from Montpellier, allows us to read a label together: species, part used, dosed marker, origin. We also ship everywhere in France and Europe. We will tell you what a product contains and how to compare it; for anything concerning your health, consult your doctor.
